1. A rotary resonator mechanism (1, 10, 20) comprising an oscillating mass (2), a flexible guide comprising at least two flexible blades (4) that cross each other at a crossing, the flexible blades connecting a stationary support (3) to the oscillating mass (2), the resonator mechanism (1, 10, 20) extending substantially in the same plane to allow the oscillating mass to perform a rotary movement around a virtual pivot, the flexible guide (1, 10, 20) extending along a main axis of symmetry (14) extending from the stationary support, through the crossing of the flexible blades and to a rigid part of a translation table at a rest position of the mechanism, wherein the mechanism (1, 10, 20) comprises the translation table (5, 15) arranged in series between the flexible guide and the oscillating mass (2), the translation table (5, 15) being joined to the flexible blades (4) and to the oscillating mass (2).
